On traits matching and the modular organization of food web and occurrence networks

open access: yesJournal of Animal Ecology, EarlyView.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Spider mite genotypes with higher growth rate suffer more from competition but exert stronger reproductive interference

open access: yesJournal of Animal Ecology, EarlyView.
Genetic correlations have strong implications for species coexistence and their evolution. Studies addressing this issue generally tackle traits associated with competition for food and those underlying reproductive interference separately, whereas it is clear that the interaction among these is key to understand the ecology and evolution of closely ...

Parasites alter host community structure in a natural experiment

open access: yesJournal of Animal Ecology, EarlyView.
Parasites can alter host communities in complex ways, but empirical data from natural systems are rare. This study decomposes the effects of an invasive parasite on natural communities of fish in Trinidad, revealing the direct, indirect, and context dependence of the invasion on host demographic rates and community structure.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

open access: yesInsect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.
